Muthuswami Dikshitar (24 March 1776–21 October 1835; IAST: muttusvāmi dīkṣitar; also known as Mudduswamy Dikshitar and, mononymously, as Dikshitar, and sometimes Guruguha), was a South Indian Hindu poet, singer, veena player, and prolific composer of Indian classical music. He was the youngest member of the Trinity of Carnatic music, alongside Tyagaraja (1767–1847), and Syama Sastri (1762–1827).
Dikshitar is credited with around 500 compositions, widely recognised for their elaborate poetic descriptions of Hindu deities and detailed architectural depictions of temples. Continuing to be widely performed in Carnatic music concerts, his music is notable for capturing the essence of ragas in the vainika (veena) style, which highlights the use of gamakas. His works are usually composed in a slower tempo (chowka kala), often incorporating middle tempo stanzas (madhyama kala sahitya).
Unlike the predominantly Telugu compositions of his Carnatic contemporaries Tyagaraja and Syama Sastri, Dikshitar's works are mostly in Sanskrit. He also composed a few kritis in Manipravalam, a literary style combining Sanskrit and Tamil.
Dikshitar was born into an Auttara Vadama Tamil Brahmin family on 24 March 1776 in Tiruvarur near Thanjavur, in what is now the state of Tamil Nadu, India, but his family traditionally traced their lineage to Virinchipuram in the northern part of the state. His father Ramaswami Dikshitar (born c. 1735), was from an Auttara Vadama family in Virinchipuram and relocated south due to the politically turbulent environment surrounding the Kanchipuram and Virinchipuram region. Dikshitar had two brothers, Chinnaswami (Cinnasvāmi; 1778–c. 1823) and Balaswami (Bālāsvāmi; 1786–1858), and a sister, Balāmba.
Dikshitar used the signature name "Guruguha" as a mudra in all his compositions, but his name is generally styled Muthuswami Dikshitar, with Muthu meaning "pearl" in Tamil, cognate to Mutya in Sanskrit. The name Muthuswami can also be linked to a deity of the Vaitheeswaran Koil in Mayiladuthurai named Selvamuthukumaraswamy, and in the 1904 Telugu publication of Sangita Sampradaya Pradarshini, Sri Subbarama Dikshitar refers to Dikshitar as Muthuswami. However, in Compositions of Muthuswami Dikshitar T. K. Govinda Rao explains that "Muddayya" is an epithet of Kumaraswami or Guha, and in Dikshitar's composition Bhajare re Chitha in Kalyani (raga), the mudra appears as "Guruguha Roopa Muddu Kumara Jananeem".
Dikshatar was educated by his father Ramaswami Dikshitar in several subjects including the Vedas, poetry, music, and astronomy. Ramaswami had trained in the veena under Venkata Vaidyanatha Dikshitar, of the lineage of Govinda Dikshitar and Venkatamakhin, an influence reflected in Muthuswami's works, which follow the Venkatamakhin raga system.
Dikshatar later moved to Manali, near Madras (now Chennai), with the support of Venkatakrishna Mudaliar, a local zamindar. He and his brothers accompanied the zamindar to Fort St. George where they were introduced to Western orchestral music and the violin. An ascetic named Chidambaranatha Yogi then took Dikshatar under his wing, and they went to the city of Benares (now Varanasi, in Uttar Pradesh). There he was instructed in music, esotericism, philosophy, and yoga. He was also exposed to Hindustani classical music, particularly the Dhrupad style, which some scholars believe influenced his later compositions.
According to hagiographical tradition, Murugan, the deity of the temple at Tiruttani is said to have placed a piece of sugar candy in Dikshitar's mouth and commanded him to sing. This marked the beginning of his music career and also led him to adopt the mudra "Guruguha", one of the many names of Murugan.
Dikshatar's first composition was "Śrināthādi guruguho jayati jayati" in the raga Maya Malavagaula and Adi tala. This song addressed the Lord (and/or the guru) in the first declension (Vibhakthi) in Sanskrit. Dikshitar later composed Kritis in all eight declensions on the Lord, glorifying Muruga in the ascetic form and having few references to the deity in the saguna form, as at Thiruthani.
Throughout his early life, Dikshitar travelled to numerous sacred temples across India, composing Kritis in honour of the deities enshrined at these sites. Many of his works praise the presiding deities of temples and incorporate references to specific characteristics and traditions of each site. Among the sites he composed at before returning to his home town of Tiruvarur were temples in Varanasi, Tirupati, Srirangam, Chidambaram, Kanchipuram, Thanjavur, Palani, Tiruvannamalai, Kalahasthi, and Srirangam.
Back in Tiruvarur he composed on every deity in the Thyagaraja Temple there, including the presiding deity Tyagaraja (a form of Lord Shiva), his consort Nilotpalambal, and the goddess Kamalambal, an independent deity of high tantric significance in the same temple complex. This is when he composed the famous Kamalamba Navavarna Kritis, filled with exemplary sahityas on the deities of the Sri Chakra. These navavarnams were in all eight declensions of the Sanskrit language and are sung as a highlight of Guruguha Jayanti, celebrated every year.
Dikshatar continued to display his prowess by composing the Navagraha Kritis in praise of the nine planets, with the sahitya of the songs reflecting a profound knowledge of the Mantra and Jyotisha sastras. The Nilotpalamba Kritis is another classic set of compositions that revived dying ragas like Narayanagaula, Purvagaula, and Chayagaula. He also attained proficiency in the veena, and the influence of veena playing is evident in his compositions, particularly the gamakas. In his Kriti Balagopala, he introduces himself as a vainika gāyaka, "a player of the veena". He experimented with the violin, as did his disciple Vadivelu of the Thanjavur Quartet, and his brother Balaswami pioneered the use of the violin in Carnatic music, making it now an integral part of most Carnatic ensembles.
Dikshitar died on 21 October 1835 (Deepavali) in Ettayapuram, where a samadhi was erected in his memory, attracting musicians and admirers of his art. Dikshitar had no children, but his disciples included several artists who carried forward his tradition, including the Tanjore quartet brothers, Ponnayya Pillai, Vadivelu, Chinnayya, and Sivanandam; the mridangam player Tambiyappa; the veena player Venkatarama Ayyar of Avudayarkoil; Tiruvarur Kamalam; Vallalarkoil Ammani; Kornad Ramaswamy; Tirukkadeyur Bharati; Thevvoor Subrahmania Ayyar; and the son of Shyama Sastri, Subbaraya Sastri.
His brothers Chinnaswami and Balaswami were also noted musicians. Chinnaswami composed some Kritis, while Balaswami adapted and pioneered the use of the Western violin in Carnatic music. The two of them were primarily vocalists and performed together as a duo singing their brother's compositions. Balaswami's grandson was the composer and scholar, Subbarama Dikshitar (1839–1906). In his Sangeeta Sampradaya Pradarshini (IAST: Saṅgīta sampradāya pradarśini), Subbarama recorded 229 of Muthuswami Dikshitar's Kritis.
Dikshitar is considered one of the Trinity of Carnatic music alongside his two contemporaries from Tiruvarur, Tyagaraja and Shyama Sastri. The Carnatic musician M Balamuralikrishna composed a song in his honor in the Raga Sucharitra, 'Cintayāmi Satatam Śrī Mudduswāmi Dīkṣitam'. Within the Raga Devamanohari, fellow Carnatic musician Koteeswara Iyer also composed the song 'Sāmi Dīkṣita' to honor Dikshitar.
Dikshitar is credited with composing around 500 works, mostly in Sanskrit and following the Kriti format. Overall, his compositions encompass a uniquely wide range of deities, broader than that found in the works of most composers in the Carnatic tradition. His works are noted for their depth, melodic sophistication, and structural precision, and his interpretations of several rāgas are regarded as authoritative references for their melodic form. While his lyrics are primarily devotional, addressed to specific temple deities, they also integrate concepts from Advaita Vedanta, with the Navagraha kritis also making references to Hindu astrology.
